This hilarious video of Jimmy Fallon and John Krasinski lip syncing makes us laugh til we’re crying. But, most of all, it makes us crave karaoke.

Luckily, it’s Friday and that means Karaoke with Peter Styles is only a few short hours away. So, if you’re craving it too, make sure you come to the Melody Bar tonight for 11pm and show John Krasinski how Katy Perry is really supposed to be sung.
